under square root of 50 ()

Step-by-step explanation:

Use pythagorean theorem. a^2 + b^2 = c^2. 5^2 is one leg, the other leg is also 5^2, and the x is what we need. So 5^2 is 25. 25 + 25 is 50. Thus, x is  (or under square root of 50), which is our answer!

correct answer:

a + bi

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
